STRAINER FOR DOWNSPOUTS.

SPECIFICATION forming part of Letters Patent No. 644,262, dated February27, 1900. Application inea December 22,1899. Serin No. 741,294. (Nomoan.)

To @ZZ whom t may concern.-

Be it known that I, BURTON ASTAIR, a citizen of the United States,residing at Harrisonville, in the county of Oass and State ofMissouri,have invented a new and useful Strainer for Down-Spouts, ofwhich the following is a specification.

i This invention relates to straine-rs, and has for one object toprovide an improved device of this class especially designed for use inconjunction with a down-spout or the like to separate leaves and otherforeign matter from the water which is to be conveyed to a cistern. Itis furthermore designed to provide a device which is complete in itselfand arranged for convenient application to any down-spout or otherpipe-line without altering or changing the latter, and finally toprovide for the convenient removal of the individual sieves or strainerswithoutremoving the casing or shell of the device from the pipe-line,and thereby facilitating the cleansing of the strainer.

With these and other objects in view the present invention consists inthe combination and arrangement of parts, as will be hereinafter morefully described,shown in the accompanying drawings, and particularlypointed. out in the appended claims, it being understood that changes inthe form,proportion, size, and minor details may be made within thescope of the claims without departing from the spirit or sacriticin gany of the advantages of the invention.

In the drawings, Figure 1 is a longitudinal central sectional view of astrainer constructed in accordance with the present invention andapplied to the lower end of a down-spout. Fig. 2 is a transversesectional view taken on the line 2 2 of Fig. 1. Fig. 3 is an enlargeddetail perspective view of one of the removable straining devices.

Corresponding parts in the several figures of the drawings aredesignated by like characters of reference.

Referring to the accompanying drawings, 1 designates the shell or casingof the device, having upwardly-divergent walls and preferablyin the formof an inverted cone, the upper and lower ends of which are open.

Located within the shell or casing are twg!) or more superposedstraining devices 2and respectively, one of which has been shown indetail in Fig. 3 ofthe drawings. Each strainer is in the form of a panhaving an upwardly and outwardly divergent marginal rim 4 and a bowedhandle 5, having its opposite end secured at diametrically-oppositepoints to the rim 4 and designed for conveniently applying and removingthe strainer. The upper and larger strainer 2 is provided with a blankmetallic bottom 6, which has a plurality of comparatively-largeperforations 7, while the lower strainer 3 is provided with a bottom ofwire-gauze or other foraminous material 8. As indicated in Fig. 1,1thedivergent rim of each strainer frictionally engages thesimilarly-inclined walls of the shell or casing 1, so as to convenientlysupport the strainer within the casing and also to provide for the readyremoval of the individual strainers.

The upper open end of the shell or casing is normally closed by means ofa removable top or cover 9, having a pendent marginal iiange 10, locatedinwardly from the peripheral edge of the cover and fitting snugly withinthe upper end of the shell or casing, while the outwardly-directed rim11 rests upon the upper edge of the casing, so as to support the coverin place. An opening 12 is provided through the top or cover and locatedadjacent to one side thereof, and rising from the walls of this openingis a pipe-section 13, which is open at its opposite ends, so as tocommunicate with the interior of the shell or casing and also totelescopically receive the lower end of a down-spout or other pipe-line14. By this construction and arrangement it will be seen that the cover9 may be elevated, as illustrated by dotted lines in Fig. 1 of thedrawings, so as to permit of the convenient removal of the individualstrainers 2 and 3 and for the convenient cleansing of the interior ofthe shell or casing.

It will be noted by reference to Fig. 1 of the drawings that the shellor casing 1 inclines upwardly and outwardly from the down-spout orpipe-line 14, so that access may be conveniently had to the interior ofthe shell and to the upper open end thereof. Also the lower end of theshell is provided with a verticallydisposed neck or pipe-section 15 forconnection with a suitable discharge-pipe 16, which is designed toconvey the clean water to a cistern, as will be understood.

IOO

In applying the device to a down-spout or other pipe-line the lower endof the latter should normally extend within the pipe-section 13 at apredetermined distance, so that the lower end of the down-spout may notinterfere with the removal of the individual strainers after the cover 9has been elevated upon the down-spout; but the latter should always becontained within the pipe-section 13, so that there may be no escape ofthe water. Moreover, the down-spout forms a guide for the cover in thevertical movement thereof.

Although but two individual strainers have been shown in the drawings,it will be understood that any preferred number of strainers may beemployed; butin any event the uppermost strainer should be provided withcomparatively-large perforations and is designed to collect leaves andother comparativelylarge articles,while the lower strainers should havesmaller perforations and are designed to separate the smaller particlesof foreign matter.

lVhat is claimed isl. In a strainer of the class described, thecombination with a down-spout or like pipeline,of a strainer,comprisingashell or casing, a removable top or cover therefor, a pipe-sectioncarried by the cover,communica`ting with the interior of the strainer,and also telescopically receiving the adjacent end of the downspout,anda strainer proper removably housed within the shell or casing.

2. In a strainer of the class described, the

combination with a down-spout or like pipeline, of a strainer,comprising a shell or casing, having upwardly-divergent walls, aremovable top or cover for the shell or casing, a pipe-section carriedby the cover, communicating with the interior of the shell or casing,and telescopically receiving the adjacent end of. the down-spout, and aremovable strainer proper supported upon the interior walls of the shellor casing, and removable through the upper end of the latter.

3. In a strainer of the class described, the combination with adown-spout or like pipeline, of a strainer, comprising a shell or casingopen at opposite ends and provided with upwardly-divergent walls, one ormore strainers proper removably housed within the shell or casin g, andcomprising a perforate bottom, an outwardly-inclined marginal rimfrictionally engaging the similarly-inclined walls of the shell orcasing and a handle for removing 5 5 the strainer, and a removable coveror top for the upper end of the shell or casing, and provided with anopening teleseopically receiving the adjacent end of the down-spout.

4. In a strainer of the class described, the 6o combination with adown-spout or like pipeline, of a strainer, comprising a shell or casingopen at its upper and lower ends, and inclined upwardly and outwardlyfrom the down-spout, one or more strainers proper removably housedwithin the shell or casing, and a removable top or cover for the latter,and provided with an opening telescopically receiving the adjacent endsof the down-spout.

5. In a strainer of the class described, the 7o combination with adown-spout or like pipeline, of a strainer, comprising a shell or casingopen at its upper and lower ends, inclined upwardly and outwardly fromthe downspout, and provided with upwardly-divergent walls, one or morestrainers proper removably housed Within the shell or casing andsupported upon the inclined walls thereof, and a top or cover removablytted to the open upper end of the shell or casing, and provided 8o withan opening, and a pipe-section rising from the wall of the said openingand telescopically receiving the adjacent end of the down-spout.

6. A strainer of the class described, comprising' an invertedsubstantially cone-shaped shell or casing open at its lower and upperends, and normallyinclined to one side of the perpendicular, one or morestrainers, located within the interior of the shell or casing, each 9ostrainer being substantially circular in form and provided with anoutwardly-inclined rim frictionally engaging the inclined walls oftheshell or casing, and a removable cover iitted to the upper open end ofthe shell or casing, and provided with an opening located at one sidethereof, and a pipe-section rising from the walls of said opening.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in Ioo the presence of two witnesses.
